A margin blade holder assembly is disclosed in which the assembly includes a housing having a first part and a second part. An elongated margin blade has a first end swivelly secured to the second housing part such that the margin blade extends outwardly from the second housing part having the ability to axially rotate in it on a slight angle and has a free second end adapted for insertion into a gap. The housing parts are secured together by connecting arms so that the second housing part is movable in a direction perpendicular to the longitudinal axis of the margin blade relative to the first housing part between a first and second position. A spring resiliently retains the second housing part, and thus the margin blade, at an intermediate position between the first and second positions. |
